Printing to an Epson printer freezes the OS

Situation:

Printing to an Epson serial printer causes the OS to freeze.

Booting with said frozen state causes the OS to freeze.

Turning off the printer lets the world continue.

We've heard this, but we can't reproduce it here. We're talking with the appropriate engineer about this and looking for other ideas. Keep tuned to the support area for information as it comes available.

Things to try:

Turn the printer off for now. Information is pending.
